Thin Layer Chromatography (TLC)
Product innovations from Whatman have made thin layer chromatography (TLC) a practical laboratory tool for both qualitative and quantitative analysis.

Features and benefits
ㆍStringent quality standards assure a consistent level of resolution, accuracy, and reproducibility
ㆍMultiple samples and standards can be run simultaneously under identical conditions
ㆍWide range of chemistries and sizes to suit your application needs
ㆍSample preparation is simplified because plates are disposable
ㆍMobile phase need not be compatible with detector
ㆍAvailable with fluorescent indicator for easy detection of many UV-absorbing compounds

Linear-K: Fast, Accurate Spotting
Whatman pioneered the linear preadsorbent layer for easy, rapid, and accurate sample application. The layer actually acts as a sponge to preconcentrate the sample before it interacts with the silica layer. In order to facilitate sample application and the preconcentrating power of the preadsorbent layer, Whatman made it thicker than the silica layer. This allows the analyst to apply sample in amounts never before attainable with standard TLC plates, and to apply dilute samples in less volatile solvents without sacrificing resolution.


Whatman TLC Product Types
Partisil K6 and K5 Absorption TLC PlatesNormal phase analysis and purification of most samples; recovery of analytes by scraping sample spots; analytical and preparative thicknesses
Partisil Reversed Phase TLC PlatesReverse phase separations and 2-dimensional reverse/normal separations
Flexible TLC PlatesCutting plates to custom sizes; recovery of analytes by cutting sample spots; normal phase or anion exchange
Diamond Series Silica TLC PlatesNormal phase; increased hardness and reflectance for resistance to solvents and reagents and for scanning densitometry
EH6 Extra Hard TLC PlatesNormal phase; very hard, smooth surface for writing on plate, high resistance to solvents and reagents
Partisil High Performance TLC PlatesNormal phase; small, uniform silica particles for maximum resolution and sensitivity


TLC Plates: Designations and Formats
Whatman has designed nomenclature as a simple and convenient way of distinguishing among the different types of plates.  Using these letter codes it is easy to define any TLC plate, for example: PLK6DF = preparative K6 silica 60Å pore diameter featuring a channeled, fluorescent plate and the preadsorbent layer.
K  Silica GelThe symbol for silica gel is K (for Kieselgel), followed by a qualifying number. K5: 10 to 12 µm silica, of pore size 150Å; K6: 10 to 12 µm silica, of pore size 60Å.
HP  High PerformanceHigh performance silica is prefixed by the letters HP: HP-K 4.5 µm silica, pore size 60Å.
KC-2, KC-18  Reverse PhaseReverse phase plates, with a bonded alkyl group, are represented by a K followed by the length of the alkyl chain: KC-18 10 to 12 µm silica, 60Å, octadecyl bonded phase
L  Preadsorbent LayerThis compresses each sample into a narrow horizontal band. Hence, it is known as Linear-K; prefix L.
D  Channeled Plates2 mm channels of clear glass separate sample lanes, preventing crossover. D indicates division.
F  Fluorescent IndicatorFluorescent plates glow bright green under shortwave UV light. Samples that absorb UV at 254 nm show as dark, quenched spots
M  Microscope SlidePlate size 1" x 3", 2.5 x 7.5 cm
P  Preparative LayerHas 500 µm or 1000 µm thickness for large sample sizes

Reverse Phase

With reverse phase plates, Whatman provides 60Å K6 with a choice of two carbon chain lengths plus Multi-K Dual Phase plates. The chain length of the hydrocarbon functional groups primarily affects retention and the ability to accommodate the water content of solvent systems. The shorter C-2 carbon chain is used for increased polarity and affinity for aqueous solutions while the longer C-18 chains give greater retention and hydrophobicity. KC-18 plates are also available with a preadsorbent zone which facilitates sample application, especially with dilute samples in less volatile solvents.
Features and benefits
ㆍProven performance, quality, and reliability
ㆍCompatibility with highly aqueous solvent systems, for greater flexibility
ㆍReady correlation with reverse phase HPLC results

Multi-K Dual Phase for Demanding Samples
Multi-K combines a 3 x 20 cm C-18 reverse phase stationary phase with a 17 x 20 cm normal phase silica stationary phase on one TLC plate. It allows two-dimensional separations of mixed polarity samples on one plate. Components are first separated by reverse phase TLC, then the plate is dried, turned 90°, and developed with a normal phase solvent mix.

Features and benefits
ㆍCleanup and analysis of complex samples
ㆍTwo dimensional TLC on one plate
